R5's outer feet, Ankle Lock, upgrade [& new centre foot wheel]...... 1.0

R5's outer feet were built, as most peoples are, to spec, well mine were as close as lol.

With a single motor wheel and caster at front to ballance, the wheel/foot assembly, then requires ankle locks to help stop the front caster from tipping the foot (due to its diameter being smaller and often 'digging in' where a larger diameter wheel is be able roll across a hole/gap). With how my outer feet and internal frame work is the locks are not the greatest, well, they're ok flat smooth surfaces, but anything slightly uneven and the 'panic stations mode' is flipped!

So the plan is to change his internal feet to better support driving him, real world situations, hopefully, reducing the worry of him tripping over.

Recent event's have confirmed that the casters are definitely the week point on any surface other than flat & smooth! So am drawing up some ideas on how best to fully lock the feet, whilst trying to keep things atheistically pleasing to the eye.

With R5 putting his [outer] feet up, I needed to replace his centre foot wheel. This may also need a future upgrade, but for now, just a new wheel was needed. The size I wanted I could only find at the original place I had got the first one from, B&Q!

The original one has worn down and although a harder compound wheel would be more suitable, the size to fit in is the limiting factor. I am looking into similar sized scooter wheels as they're material is harder, so won't wear out as much! [W.I.P.]

Spent bout 45 mins, looking for suitable size/thickness wood, figuring out how to best fit it..... When I found some metal strips that would be perfect. So bent one to the angle required and then marked for cutting.

I found a pair of M10 cap head bolts that should do the job of holding the angles in place. I just need some nylock nuts.
